It is the policy of the Legislature that foster care should be a temporary method of care for the children of this state, that children have a right to a normal home life free from abuse, that reunification with the natural parent or parents or another alternate permanent living situation such as adoption or guardianship is more suitable to a child’s well-being than is foster care, that this state has a responsibility to attempt to ensure that children are given the chance to have happy and healthy lives, and that, to the extent possible, the current practice of moving children receiving foster care services from one foster home to another until they reach the age of majority should be discontinued.
